ABSTRACTThis course outline was prepard to help apprentice
drywall installers and teachers of drywall finishing courses to learnor teach the skills necessary for the apprenticeship course inBritish Columbia. The course outline consists of 11 tracks (units)that cover the following topics: estimating, job inspection, safety,applying bead, filling compounds, taping, filling, texturing, makingrepairs and corrections, maintaining equipment, and job economics.Each unit consists of 3 to 12 skills outlines. The page format forthe skills outlines has a statement of the skill at the top, followedby the performance objective, and a list of procedures. Theprocedures detail the steps and knowledge needed to carry out theobjective. Opposite each procedure are criteria that give theacceptable standard for how well the procedure is to be done. Theoutline can be used by students as a guide to accepted standards andby teachers as a lesson plan. A drywall finishing skill profile chartis included. (KC)

The Drywall Finishing Apprenticeship Course Outline is produced usingtho DACUM process, a systematic model for developing career, technical,and vocational training programs.
The first step in the process is to hold a DACUM Workshop. The DrywallFinishing DACUM workshop was held in June, 1976, and was attended bydrywall finishing journeymen, representatives of the Drywall FinishingJoint Board and the Carpentry Apprenticeship Joint Board of B.C., andomfloyers. Participants for a workshop are selected who have a realisticunderstanding of the day-to-day activities carried out on the job andare familiar with new technology in the field. The product of a DACUMWorkshop is a Skill Profile Chart; it lists the essential skills neededby a ocrson to do a job, in this case, the job done by journeymen dry-wall finishers.
Once a skill profile chart is approved, the next step in the DACUMprocess; is to write a Course Outline. For each skill on the chart (ormore remistically, for each skill on the chart possible to teach in atraining program) a Performance Objective is devised, that is, a taskthat the trainee or apprentice must perform, and perform to certainc,tandards, to demonstrate having the skill. When trainees can satis-facterily do all the performance objectives in the course outline, thenthey are considered fo have the skills required to complete the trainingprogram.
The paw format for the Drywall Finishing Course Outline has a statementof the sk"11 at the top, under it the performance objective, and then
f list of Procodures. The procedures detail the steps and knowledgeneeded 10 earn/ oui the objective; they are, in other words, the partswhole the objective is the whole. Opposite each procedure are Criteriawhich give the acceptable standard for how well the procedure is to bederv..
This course outline can be used by both students and instructors. Studentswill find 11 helpful in directing their studies and practice, and as aguide to accepted standards. Instructors can use the outline as a lessonplan. Some modifications to the performance objectives may be necessarybecause of training program restrictions such as money, space and equipment.However, any modifications should retain the interil of the orobjective and have criteria of equal standards.
FOR
WA
RD
The Drywall Finishing Apprenticeship Course Outline is
issued by the Ministry of Labour for apprenticeship
training classes.
Apprentices attend these classes in
accordance with the regulations of the Apprenticeship
and Training Development Act.
The outline was prepared
by Gerald Lengert, a drywall finishing instructor at
Pacific Vocational Institute.
Mr. Lengert was advised
and assisted by the Drywall Finishing Trade Advisory
Committee, a body which consists of representatives
from both labour and management, and the outline has
been approved by the commiltee.

Choosc method of elevating worksurface.
Determine method of texturingand undercoating.
CRITERIA
. Drytaping is slow but requires fewtools - and is efficient in dreasthat are hard to get at.
. Hopper method is faster than dry-taping but work must be split intotops and bottoms.
. Machine allows all work to be donefrom the floor thus speeding uptaping process.
Stilts are safe up to 600 mm.
2. Baker-type scaffolds good up to 2 m.
3. Rolling tower can be jointed forheights above 2 m.
. Sa... horses and planks can be used
but lime is spent moving and settingup.
5. Ladders can be used if a small areaat height over 2.4 m to 5o reached.
. Hand-held hopper good for areas under300 m2.
. Hand-held hopper best for orange-peeland splatter type finish.
. Rota - stator pump best for aggregate
type textures over 300 m2.
Paint roller best for 300 m2 andunder.

THE DACUM APPROACH
DACUM is a systematic model of program development used in designingcareer. technical and vocational training programs. The first step in theprocess is to establish the skills expected of a graduate entering em-ployment. These skills are generally specified by a representative employergroup in a workshop conducted by program development specialists. Theproduct of this activity is a skill profile chart. This chart is then circulatedboth to the participants and to a number of other employers for review prior tofurther development.
The next step is to specify learner-centred performance objectives. These in-dude not onty the skills a learner must demonstrate but also the conditionsunder which the Skill is to be performed and the criteria used to determine theacceptable standard of performance.
Once the performance objectives have been set. there are three importantsteps to complete the development process. These are generally undertakenby an instructor or group of instructors. in the following order:
1) Appropriate evaluation instruments are chosen 'or created to assessso student capability in relation to the specific objectives of the program.
2) A variety of suitable instructional techniques and teaming experiencesare chosen to facilitate learning of the skills and knowledge required tomeet the objectives.
F
3) Instructional resources (texts. films. models. and other learning aids)are selected or created.
4
READING THE SKILL PROFILE CHART
A skill profile chart (often referred to as a DACUM Chart). is a graphicrepresentation of the essential skills expected of a student graduating from aspecific career. vocational or technical program.
Broad areas of employee responsibility are Shown in the boxes on the ieft ofthe chart. These are called "general areas of competence". The tasks orskills related to each are sequenced along the horizontal track to the right ofthe general area of competence.
